The average price for a gallon of regular unleaded gasoline is $2.229 at self-service pumps in the Ocean State, the same as last week, according to AAA's weekly survey.

A year ago the average price was 30 cents less, $1.92.

Rhode Island drivers are paying seven cents less than the national average of $2.299, according to AAA.

Lloyd Albert, senior vice president of public and government affairs for AAA Northeast, says prices are likely to increase with the warmer weather.

“As spring arrives, it’s likely we will see pump prices start to tick up. People drive more in warmer weather, leading to greater demand for gasoline. And the annual seasonal switch from the winter fuel blend to the more expensive to produce summer gasoline blend also adds a few pennies to prices at the pump,” Albert said in a AAA press release.

AAA's survey found a 26-cent range in price for regular unleaded, from a low of $2.099 to a high of $2.359.

AAA's survey also found the following average prices: $2.499 for mid-grade gasoline; $2.709 for premium gasoline; and $2.539 for diesel fuel.
